CVE-2026-18405 · Severity: high · CVSS 7.2 · Published 2026-09-18

Jeg Kit for Elementor is a WordPress plugin that provides advanced widgets and templates for the Elementor page builder. The plugin is vulnerable to stored cross-site scripting (XSS) through comment content, allowing unauthenticated attackers to inject malicious scripts that execute when users view affected pages. Exploitation requires that the page contains a legitimate Jeg Kit Countdown widget, which triggers the vulnerability when processing forged widget markup in comments.

## Technical details

The vulnerability is a stored cross-site scripting (XSS) flaw caused by insufficient input sanitization and output escaping of comment content. An unauthenticated attacker can inject arbitrary JavaScript into page comments using forged Jeg Kit Countdown widget markup. When a page containing a legitimate Countdown widget is accessed, the widget's frontend initialization script processes all matching DOM elements on the page—including the attacker's injected markup in comments—and executes the malicious script without proper validation. This affects all versions up to and including 3.2.16. The attack requires a page with an active Countdown widget to trigger script execution.
